To start
introduction
As a start example, you can make a home domain system with a nano computer raspberry Pi3 B+, equipping it to manage 433 MHz equipment and equipment zigbee. I chose the Martiaticz Marketball software to handle the set.
** The raspberry Pi3 B+ has for benefits: **
-
Its low price
-
Very comfortable computer power for home automation.
-
reduced consumption.
-
No need for a fan.
-
Connectability provided: Ethernet Port, 4 USB ports, WiFi, Bluetooth, GPI ports.
** The interest of the 433 MHz is: **
-
We have allowed us worldwide for decades.
-
As a result, there are very cheap material.
His disadvantages are:
-
There is no defined protocol, each manufacturer does what he wants.
-
The protocol used is rarely bidirect.
** ZigBee’s interest is: **
-
It was designed to enable the construction of cheap modules, as a result the prices gradually fall.
-
It uses an open, secure and bidirectional protocol.
-
Each module can serve as a relay to increase the scope.
-
It uses a range of international frequency and to manage a large number of modules.
-
It was chosen by important brands such as Philips ( System HUE ), IKEA ( System TRÅDFRI ), LeGrand, Xiaomi, and many more …
